Filed: 1984-04-13
Abstract: PURPOSE:To provide the titled compsn. which can reduce the emission of smoke and the quantity of hydrogen chloride released during combustion without lowering tensile strength, thermal aging characteristics and water resistance, by adding a hydrotalcite compd. to a chlorine-contg. polymer and crosslinking it. CONSTITUTION:A flame-retardant resin compsn. is obtd. by adding 10-150pts.wt. hydrotalcite compd. (A) (e.g. natural product of formula I or a synthetic product of formula II) to 100pts.wt. chlorine-contg. polymer (B) (e.g. PVAc, polyvinylidene chloride or chlorinated PE) and crosslinking it in the presence of dicumyl peroxide. Though the chlorine-contg. polymers are flame-retardant and superior in oil resistance, mechanical characteristics, etc., they have disadvantages in that they emit volumes of smoke and evolve a large quantity of hydrogen chloride during combustion. By adding component A and crosslinking the polymer, the emission of smoke and the quantity of hydrogen chloride evolved can be reduced during combustion at the time of a fire and damage can be reduced without detriment to tensile strength, thermal aging characteristics and water resistance inherent to the chlorine-contg. polymers.

Filed: 1981-05-19
Abstract: PURPOSE:To obtain a lens which has no breakage with a light weight and comparatively large surface, by filling the water into a convex or concave transparent synthetic resin bag and making use of the water refractive index. CONSTITUTION:The water 2 is filled in a convex or concave transparent bag 1. The light or heat has the refraction to water 2 and is focused (convex) or dispersed (concave) to the focus. The bag 2 is made of the soft synthetic resin and has a water charging port to facilitate the charge-in and take-out of the water. The water is filled into the bag only when it is used as a lens, and the water is taken out of the bag not in use as a lens. The bag with no water can be folded for the carrying purpose. When a refractive index approximate to or larger than that of an optical lens is desired, another transparent liquid (benzene, glycerol, etc.) having a large refractive index is used in place of the water. The thickness of the lens is varied by using a flexible material to the bag 1 and controlling the quantity of the water. Thus the focal distance is variable.
